What are the Audi R10 TDI Le Mans Proto type LMP1 doing differently that the engine doesn't produce any smoke? I'm clueless when it comes to diesel technology.
But, as we have emphasized in this discussion, providing enough oxygen is paramount. Elevated boost is certainly in the formula. A friend who is a BMW/Audi tech thinks the Le Mans racers use elevated injections pressures well above the 2000 bar of road cars. This gives them more injection timing control and provides exceedingly small droplets to burn. They don't have to worry about extended reliability in the range of years. And remember, even though we don't see "smoke" there are still the SMPs which as Oil Pan4 pointed out, you can not see or smell.
